  • Spin Dependent Gravitational Tail Memory in $D=4$.- [PDF] - [Article]

    Debodirna Ghosh, Biswajit Sahoo
     

    We attempt to derive the leading spin dependent gravitational tail memory, which appears at the second post-Minkowskian(2PM) order and behaves as $u^{-2}$ for large retarded time $u$. This result follows from classical soft graviton theorem at order $\omega\ln\omega$ as a low frequency expansion of gravitational waveform with frequency $\omega$. First we conjectured the result from the classical limit of quantum soft graviton theorem up to sub-subleading order in soft expansion and then we attempt to derive it for a classical scattering process without any reference to soft graviton theorem. In the direct derivation, we found some extra contribution in addition to the conjectured result, which we expect to go away but could not able to show it.
